A four-inch Portland cement concrete V-ditch is positioned adjacent to a proposed platform. The drainage channel features reinforced construction utilizing six-by-six ten-slash-ten welded wire mesh. The section dimensions require a minimum twelve-inch depth, a twelve-inch horizontal width from the centerline to the platform edge, and a six-inch vertical offset from the top of the platform to the channel invert. The outer edge matches the existing slope with a minimum twelve-inch horizontal dimension from the top slope break.
